Continuous multi-analyte dialysis monitoring and dosing
This technology uses Raman spectroscopy — a laser-based technique that identifies molecules by how they scatter light — to analyze fluids produced during dialysis, such as spent dialysate or urine, without needing traditional blood draws or lab tests. By shining a laser directly on dialysis tubing fluids or samples taken from the circuit, the system detects and tracks multiple waste molecules simultaneously and measures how quickly each is being cleared from the patient's body. These clearance patterns are then used to assess how well the current dialysis session is working and to automatically adjust future treatment frequency, duration, or flow rates. The result is a real-time, data-driven feedback loop that personalizes dialysis prescriptions based on what each patient's body is actually doing during treatment.
What you could build
A sensor module integrated into dialysis machines or tubing sets that continuously analyzes treatment fluid chemistry and feeds multi-analyte clearance data into a clinical decision-support dashboard; dialysis clinic operators and nephrologists at outpatient dialysis centers would be the primary buyers.
Who in Virginia should care
Virginia's large network of DaVita and Fresenius outpatient dialysis clinics, plus Virginia-based health systems like Inova and VCU Health with nephrology programs, would be natural early-adoption partners or pilot sites.
Readiness: Prototype likely
Concept — described but not yet demonstrated. Lab validated — supported by experimental results in the patent. Prototype likely — the text describes a built, working embodiment.
Readiness is inferred from the patent text, not from a lab visit.
